Charger 24 is connected with the electrode line PL and the negative line NL that are configured between SMR14 and PCU16 via charge relay 26.Charger 24 comprises the on-off element of electric power conversion use, and according to the control signal from ECU28, and the electric power being supplied to from external power supply 30 is converted to predetermined charging valtage (direct current).Be supplied to electrical storage device 12 via charge relay 26 by the electric power of voltage transitions by charger 24, thereby make electrical storage device 12 be implemented charging.Charge relay 26 is arranged between charger 24 and electrical storage device 12, and implements the be electrically connected/disconnection between charger 24 and electrical storage device 12 according to the signal EN from ECU28.
ECU28 is by by CPU(Central Processing Unit: central process unit) in carry out the hardware handles that software that pre-stored program implements is processed and/or implemented by special electronic circuit, and charger 24 and charge relay 26 are controlled.ECU28 carries out the ON/OFF operation of the CCID34 of EVSE32 in the time of external charging.Particularly, ECU28 is by operating and CCID34 is carried out to remote operation the current potential of the pilot signal CPLT accepting from EVSE32.And ECU28 generates the electric power instruction of the starting/stopping instruction of charger 24 or the expected value of expression charging power etc., and exports to charger 24.
At this, ECU28 can be at three kinds of following mode of operations, i.e. awakening mode, sleep pattern and intermittently carry out work under originate mode.Awakening mode is the state that ECU28 has started completely, and in the time of the starting of external charging and in implementation, ECU28 becomes awakening mode.Sleep pattern is the state that ECU28 has stopped in the time not carrying out external charging, and in the time of sleep pattern, the major clock in ECU28 has also stopped, thereby has suppressed power consumption compared with awakening mode.Intermittently originate mode is, mode of operation when charging cable still connects after the end of external charging.In intermittence originate mode, standby mode and awakening mode are alternately switched termly.Although standby mode and sleep pattern are similarly the state that ECU28 has stopped, the major clock in ECU28 carries out work.Thus, can switch to termly awakening mode.In addition, in sleep pattern and standby mode, accordingly, sleep pattern one side's power consumption is less for the amount stopping with major clock.
Before detecting the input of pilot signal CPLT, ECU28 becomes sleep pattern.And if detected the input of pilot signal CPLT in the time of sleep pattern, ECU28 will become awakening mode.Specifically, when sleep pattern, the major clock of ECU28 is in stopping, and ECU28 accepts pilot signal CPLT as hard interruption.And, when the positive rise that has detected pilot signal CPLT (can be also falling edge.) time, mode of operation will shift as awakening mode from sleep pattern, thus ECU28 starting.In addition, pilot signal CPLT is, in the time that the adaptor union 38 of charging cable is connected on entrance 22, is imported into the signal in vehicle 10, also can be understood as the signal of the implication that represents the charging of user's requirement.
In the time that external charging finishes (charging cable is still coupled condition), ECU28 will become intermittently originate mode.Under intermittence originate mode, even major clock also carries out work under the standby mode of dormant state, thereby ECU28 is started termly, and for to external charging restart or the disconnection of charging cable etc. checks and pilot signal CPLT is monitored.
In the connection of charging cable, as described later, pilot signal CPLT vibrates.And, in the time detecting the vibration of pilot signal CPLT and stop, being judged as charging cable and being disconnected (or external power supply 30 has a power failure) from vehicle 10, thereby ECU28 becomes sleep pattern.Thus, the interruption that the starting conditions of ECU28 (awakening mode jump condition) is switched to pilot signal CPLT from regular starting at intermittence detects.In addition, owing to stopping when the vibration of charging cable pilot signal CPLT when vehicle 10 is disconnected, therefore the pilot signal CPLT of vibration not can be understood as the signal of the implication that represents that charging that user proposes finishes.
Fig. 2 is the functional block diagram of the ECU28 shown in Fig. 1.With reference to Fig. 1, ECU28 comprises charging control section 52, mode of operation control part 54, major clock 56 together with Fig. 2.Charging control section 52 is accepted pilot signal CPLT, cable connects signal PISW, the voltage VAC of electric power being supplied to from external power supply 30 and each detected value of electric current I AC.Voltage VAC and electric current I AC are detected by not shown voltage sensor and current sensor respectively.In addition, charging control section 52 is accepted clock signal from major clock 56.And charging control section 52 generates signal EN for driving charge relay 26 according to this each signal and for driving the signal DRV of charger 24, and signal EN, the DRV of this generation are exported to charge relay 26 and charger 24 respectively.In addition, charging control section 52 by the practice condition of external charging (at least in the execution of external charging/do not carry out) notice to mode of operation control part 54.
Mode of operation control part 54 is accepted pilot signal CPLT and is connected signal PISW with cable.In addition, mode of operation control part 54 is accepted the practice condition of external charging from charging control section 52, and accepts clock signal from major clock 56.And mode of operation control part 54 is controlled the mode of operation of ECU28 according to these each signals.
Fig. 3 is the figure that represents the passing of the mode of operation of ECU28.With reference to Fig. 2, initial, setting mode of operation is sleep pattern together with Fig. 3.In the time of sleep pattern, not from mode of operation control part 54 to major clock 56 output services instructions, thereby major clock 56 stops.The hard state interrupting of the wait of mode of operation control part 54 in pilot signal CPLT.
